Here is the manual from their website for rpod models 2015 and newer. I don't see anything about a monthly pressure test, only a vague reference that you should suspect a leak if the pump "is running" when the faucets are off. That is certainly not a scheduled maintenance inspection and requires you to be dry camping and to interpret what "is running" means. For how long and how often? My pump turns on every once in awhile for a short time either from a slightly leaky pump check valve or a slowly dripping faucet. I doubt it would run more for a tiny pinhole leak from a staple. Many folks always camp with city water and never use their water pumps. 

Then under monthly maintenance it says "check hoses, fittings, and connections for leaks and wear".  That clearly reads like a visual inspection, nothing about running the pump for a pressure test.
